An Analytical Solution for Signal Background and Signal to background Ratio for a Low Frequency Active Sonar in a Pekerisch Waveguide Satisfying Lambert's Rule
conference paper
Previously published equations for the time dependence of the echo and reverberation in a Pekeris waveguide are combined with an expression derived for surface-generated noise. These closed form solutions are applied to the calculation of signal to reverberation ratio and signal to total background ratio for three CW pulses with centre frequencies between 250 Hz and 3.5 kHz. The scenario considered is Problem A2.I from the ‘Validation of Sonar Performance Assessment Tools’ meeting of the Institute of Acoustics, held in Memory of David E. Weston, in April 2010. This scenario involves the detection of a spherical target in a Pekeris waveguide, against a background of rain noise and Lambert-rule reverberation from the seafloor
